All Box stems are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars we have focused our attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector we have reciprocated with an augmented stem interface with greater surface area. We’ve done this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars we have contributed to increased pedaling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar-to-stem deflection and the consequences can be poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: In this particular model stem we’ve modulated the Oversized formula to emphasize pedaling stiffness. We have transferred material specifically to sectors that experience sudden stress from pulling up on the handlebars. You’ll feel a difference in your acceleration. These stems are engineered for the larger-sized racers. -Material: 6061-T6 Aluminum -Process: Cold-Forged -Hardware: Chromoly Clamping Bolts -Finish: Anodized w/Laser-Etched Graphics Weight: -48mm: 280 g / 9.8 oz -53mm: 290 g / 10.2 oz

When stiffness and weight are the top on your list, you want Ritchey's SuperLogic C-260 Carbon Stem. This revolutionary design starts with a bar clamp that wraps a full 260-degrees around the handlebar to distribute clamping stress evenly through the handlebar, faceplate, hardware and stem body. Ritchey's first full-carbon stem, the C-260 features high-modulus carbon for stellar strength-to-weight ratio that translates into a solid but forgiving ride. And, the steer tube clamp uses three bolts and a curved slot to reduce clamp stress on the steer tube, so you can run carbon bars and a carbon steerer with no problem.

You really can have it all-the WCS C220 stem rivals the performance of the revolutionary C260 stem design, but it's quicker and easier to install and remove thanks to a press-fit handlebar clamp interface and forward-facing hardware.
